If you mean the pentacle, or five-pointed star, there is a full description in the book called THE DAVINCI CODE. It is very thourogh, but I will give some of the meanings. The five points represent the five stages of womanhood. Some Christians say that they represent the five elements:earth, fire, wind, water, and spirit. It is also perfectly formed by the orbit of Venus every four years. That is the cycle on which the Olympics is held, and the pentacle very nearly became the official sign instead of the five inter locking rings. Hope this helps!!!
